This paper explores the role dynamic textile displays play in relation to personal style: What does it mean to wear computationally responsive clothing and why would one be motivated to do so? We developed a novel textile display technology, called Ebb, and created several woven and crochet fabric swatches that explored clothing-specific design possibilities. We engaged fashion designers and nondesigners in imagining how Ebb would integrate into their design practice or personal style of dressing. Participants evaluated the appeal and utility of clothing-based displays according to a very different set of criteria than traditional screen-based computational displays. Specifically, the slowness, low-resolution, and volatility of Ebb tended to be seen as assets as opposed to technical limitations in the context of personal style. Additionally, participants envisioned various ways that ambiguous, ambient, and abstract displays of information could prompt new experiences in their everyday lives. Our paper details the complex relationships between display and personal style and offers a new design metaphor and extension of Gaver et al. s original descriptions of ambiguity in order to guide the design of clothing-based displays for everyday life.
We propose cutting as a novel paradigm for ad-hoc customization of printed electronic components. As a first instantiation, we contribute a printed capacitive multi-touch sensor, which can be cut by the end-user to modify its size and shape. This very direct manipulation allows the end-user to easily make real-world objects and surfaces touchinteractive, to augment physical prototypes and to enhance paper craft. We contribute a set of technical principles for the design of printable circuitry that makes the sensor more robust against cuts, damages and removed areas. This includes novel physical topologies and printed forward error correction. A technical evaluation compares different topologies and shows that the sensor remains functional when cut to a different shape.
Au(Si)-filled β-Ga2O3 nanotubes were fabricated by an effective one-step chemical vapor deposition method. The Au(Si) interior was introduced by capillarity. Linear thermal expansion of Au(Si) with a coefficient of thermal expansion (CTE) as high as 1.5×10−4(1∕K) within single crystal Ga2O3 shell up to 800°C was observed by in situ transmission electron microscopy. The high CTE is correlated to partial melting of Au(Si). As Ga2O3 possesses excellent thermal and chemical stability, the structure can be used as a wide range high-temperature nanothermometer within localized regions of nanosystems.
Solid‐Pb‐filled ZnO nanotubes are synthesized and tested for use as nanothermometers. The expansion of the filling with increasing temperature (see figure) — or the corresponding changes in capacitance — can be measured and related to temperature. The advantages of this nanothermometer are extremely low fabrication costs, superior reliability, and lower demands on structural integrity of the outer shell compared to nanothermometers based on liquid fillings.
